Blisters When You Walk Higher Miles. Walking 10 miles (over 3 hours), even if you are used to walking for six miles, is more of a challenge. You can do it, but most people are likely to develop blisters in new places. Shoes and gear that worked fine for two hours may not be ideal for four hours.
How the Aurora Borealis occur. The Northern Lights are caused by the interaction of the solar wind - a stream of charged particles escaping the Sun - and our planet's magnetic field and atmosphere.
The Northern Lights, as the name suggests, are especially related to the polar regions. They occur most frequently in a belt of radius 2500 km centered on the magnetic north pole.This so-called auroral zone extends over northern Scandinavia, Island, the southern tip of Greenland and continuing over northern Canada, Alaska and along the northern coast of Siberia.e associate the Northern Lights with wintertime, although in reality they are present the year round; it's just that we can't see them when the nights are light as the background sky has to be fairly dark.
